Virtualization on Miro's World

VisualVM inside Docker container

The idea / motivation
#

In order to run VisualVM from predefined configuration you need to point the app to the user directory. This directory takes about 20MB, but 90% of the the content is actually generated or repeated.

➜  4devops-visualvm git:(master) du -sh tw-sl/*
244K    tw-sl/config
7.3M    tw-sl/modules
 52K    tw-sl/repository
4.0K    tw-sl/update
104K    tw-sl/update_tracking
 11M    tw-sl/var

➜  4devops-visualvm git:(master) du -sh tw-wool/*
248K    tw-wool/config
7.2M    tw-wool/modules
 60K    tw-wool/repository
4.0K    tw-wool/update
104K    tw-wool/update_tracking
 11M    tw-wool/var

➜  4devops-visualvm git:(master) du -sh tw-wool
 19M    tw-wool

The only part that is specific and worthy of maintaining in the Git repo is repository

Starting ACC in VM

Wed, 15 Jul 2015 11:22:48 +0800

The ACC is installed in default location: ~/ATG/ACC11.1

This does not work OOTB. You must set 2 additional ENV properties

cd ~/ATG/ACC11.0
export ACC_HOME=`pwd`
export JAVA_VM=/usr/java/jdk1.7.0_51//bin/java
bin/startClient &

Starting from dyn/admin
#

The start in separate VM works OK.

Start in server VM brings errors message very often complaining of malformed Help URL.

The issue is documented here: http://stackoverflow.com/questions/20868244/how-to-fix-malformed-help-url-while-opening-acc-atg - for JBOSS.

ATG Development using 'hidden' VM

Brief description of my latest setup I use for CPL and LCH - in case I forget it or somebody wants to replicate it.

Inspiration for the setup came from https://www.youtube.com/watch?feature=player_embedded&v=cPt_1Vga-Nk

Motivation - issues with VMs
#

VMs are great - they allow “packaged” dev environment and quick start for the new member of the team. Start a VM on local or remote host, connect with VNC or Remote Desktop and you are in business.
